Definitions

  • the present invention relates to a dispensing cartridge with storage cylinder and delivery piston according to the preamble of claim 1.
  • a dispensing cartridge is known from FR-A-2 626 248 and is preferably intended for cosmetic products.
  • the delivery piston is double-walled and the vent hole is closed by a pin working as a valve. The air escaping when the delivery piston is pushed in flows through the vent hole and escapes through a gap on the side, which is closed by the piston end.
  • Such a delivery plunger or closure of the vent hole is not suitable for discharge cartridges for industrial purposes with environmentally harmful fillers and, moreover, exact control of the complete venting is not possible, so that either the venting is incomplete or the filler compound can escape to the outside.
  • a discharge cartridge which also has a vent hole and a delivery piston bottom, the bottom surface of which is continuously recessed towards the vent hole and in which the vent hole is closed by a closure independent of the delivery piston .
  • this feed plunger filling compound can reach its rear surface when it is pressed in.
  • FIG. 1 shows the discharge cartridge 1 with the storage cylinder 2, which is closed at the bottom by a lockable outlet 3.
  • the cylinder 2 in FIG. 1 already contains the precisely weighed amount of the filling compound 4.
  • a delivery piston 5 in the wall of which an O-ring 6 is inserted in order to seal it.
  • the delivery piston is usually made of a dimensionally stable material. Instead of an O-ring, an elastic sealing lip molded onto the piston rim can be provided, which rests against the inner wall of the cylinder. The contents of the cartridge are stored in the storage cylinder and later pressed out through the outlet when in use.
  • the bore 9 is closed by a closure 10, which in the present example, see FIG. 2, can be locked in an annular groove 13 by means of a bead 11 on the head 12 of the closure.
  • the bead is attached to a resilient collar, which ensures that the bead is pressed against the annular groove 13.
  • the vent hole 9 has, see Figure 3, seen from a certain height from the bottom surface, a cross-sectional constriction, for example in the form of a cross recess 14, the constriction serving as a restrictor against rapid pouring out of the filling compound after the filling process has ended. This ensures complete ventilation.
  • a cross-sectional constriction for example in the form of a cross recess 14, the constriction serving as a restrictor against rapid pouring out of the filling compound after the filling process has ended. This ensures complete ventilation.
  • the slots or inner grooves can also be designed differently and in different numbers.
  • the bottom surface of the piston has an arrangement of radially extending, slot-shaped depressions 15, which open out at the vent hole.
  • the piston can have radial ribs 16 above its bottom surface. The radially extending, slot-shaped depressions 15 and the ribs 16 are shown and drawn in all details in the aforementioned application.
  • a ventilation chamber 17 is arranged around the cylindrical ventilation bore 9, which is formed by a circumferential sealing cylinder 18 which is arranged at a distance from the wall 19 which forms the cylindrical ventilation bore 9 and in the inner surface of which the annular groove 13 is formed.
  • slots 20 are made, from which the filling compound can emerge, as shown in FIG. 2.
  • the filling compound can be filled, for example, from below through the open outlet 3, the exact volume of this compound being introduced by a metering device.
  • the outlet 3 is then closed.
  • the delivery piston is inserted into the cylinder from above and pressed down against the filling compound until all air has escaped from under the piston head through the vent hole with throttle.
  • the complete ventilation can be visual are followed and occurred when the filling compound emerges from the slots 20 of the wall 19 and is pressed into the overflow chamber.
  • the closure 10 can then be pressed in until the bead 11 engages in the annular groove 13 and the shoulder 21 rests on the closure on the end face 22 of the wall 19. In the position shown in FIG. 2, the discharge cartridge is ready to enable the filling compound to be discharged precisely.
  • the filling compound can, of course, also be filled in on the delivery piston side when the outlet 3 is closed, this depending on the filling system and the metering devices.
  • a closure screw can also be used, which can be formed similarly to the aforementioned EP-A-344 491, but must have a head which seals the overflow chamber.
